Physical Geology
and Historical Geology
• Examine materials making up the Earth and seek to
understand the many processes operating beneath and
upon its surface.
• It is a dynamic ever changing planet due to internal
forces that create earthquakes, mountains, volcanoes
etc. and external processes like weathering, erosion,
formation of a diversity of landscapes.
• Rocks and minerals form in response to these
processes;
• Therefore, their interpretation is essential to
understand our planet.
